NAME
unicode_uc, unicode_lc, unicode_tc, unicode_convert_tocase - unicode uppercase, lowercase, and titlecase
character lookup
SYNOPSIS
#include <courier-unicode.h>
char32_t unicode_uc(char32_t c);
char32_t unicode_lc(char32_t c);
char32_t unicode_tc(char32_t c);
char *unicode_convert_tocase(const char *str, const char *charset,
char32_t (*first_char_func)(uncode_char),
char32_t (*char_func)(uncode_char));
DESCRIPTION
unicode_uc(), unicode_lc(), unicode_tc() return the uppercase, lowercase, or the titlecase equivalent of
the unicode character c. If this character does not have an uppercase, lowercase, or a titlecase
equivalent, these functions return c, the same character.
unicode_convert_tocase() takes the string str in the character set charset. first_char_func and
char_func, each, should be unicode_uc, unicode_lc, or unicode_tc. unicode_convert_tocase() returns a
malloc()ed buffer. The first unicode character in str gets processed by first_char_func, and all other
characters by char_func.
